带有三电极直流氩等离子焰装置和中阶梯光栅单色器的SpectraSpan ⅢA型直读光谱仪,由于有良好的稳定性和高的分辨率,已引起人们广泛的注意。并进行了一系列的研究。在自然水和排灌水中痕迹元素的同时测定中,得到了良好的结果。土壤中大量元素的分析,是一件量大费时的工作。
The SpectraSpan IIIA direct reading spectrometer with a three-electrode DC argon plasma flame apparatus and a middle-stepped grating monochromator has drawn wide attention due to its good stability and high resolution. And conducted a series of studies. Good results have been obtained in the simultaneous determination of trace elements in natural and irrigated waters. Analysis of a large number of elements in the soil, is a large amount of time-consuming work.
